LoginGives brief details of three ventilation retrofits that showed good results. The case studies are selected from a group of ten carried out by the Canada Mortgage and Housing Corporation.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Gives brief details of the Canadian Construction Materials Centre's recent evaluation of three new ridge vent products made of either three-dimensional polymeric matting or moulded plastic.
Describes a new hospital whose wards will all be naturally ventilated. It is a highly serviced facility, with services accounting for 44% of the total construction cost of the building, but naturally ventilated wherever possible.
The Eden project consists of two massive 'biomes' situated at the bottom of a former clay pit in Cornwall, UK. They mimic a 'humid-tropic' and a 'warm-temperate' environment and each houses a wealth of plant life.
States that to be effective, insulation must be installed correctly. Studies have shown that even small imperfections in how insulation is installed will significantly reduce its performance.
Designing a ventilation system for a laboratory is challenging not only because these facilities consume a lot of energy and may contain materials that are toxic, flammable, explosive, infectious, or radioactive, but because standards and codes co
The provision of underground parking facilities (UPFs) has become a necessity particularly in densely populated urban areas and business districts. Indoor air quality (IAQ) in such facilities is of great concern due to vehicle induced emissions.
Results from pre- and postconstruction radon measurements in a new housing development are presented. The houses were built in an area that had not been previously associated with elevated indoor radon concentrations.
States that to control humidity it is necessary to remove moisture load from ventilation air.
States that there are problems involved with the use of traditional instruments such as vane anemometers and pitot tubes when measuring airflow rates in HVAC systems in order to balance air distribution.
Investigates the ventilation efficiency of different ventilation patterns arranged by two inlet and two outlet diffusers at different locations.
The article discusses relationships between indoor and outdoor levels of various air contaminants (nitrogen monoxide, nitrous oxides, sulphur dioxide and ozone), in ten non-smoking residential buildings in Hong Kong.
Describes a simplified numerical model, POMA (Pressurized zOnal Model with Air-diffuser, intended to predict the airflow pattern and thermal distributions within a room.
Describes how a Wisconsin engineer is using basic thermodynamic principles and readily available equipment to design innovative heating, ventilating and air conditioning systems.
Many buildings under construction or renovation today require a smoke-control system, either to gain building regulations approval or, to protect the building, its contents and occupants, and to offer assurance of business continuity in case of fi
Describes how a computational fluid dynamics code was used to predict temperature and flow fields in recessed spaces outside high-rise residential buildings housing condenser units for window air conditioners.
A study obtained steady-state solutions for Rayleigh number on flow structure of buoyant flow in a roof of triangular cross-section. The heat transfer was also investigated.
The residential building described is an experimental low energy home, using a hybrid system with natural energy resources and unused energy. Describes its construction and evaluation.
Analyses present and historical Thai houses in terms of climate, culture and technology, as background to an investigation of the potential for use of natural ventilation as a passive cooling system for new house designs.
Discusses good control of heating, ventilating and air conditioning systems as the best way to improve energy efficiency in air conditioned buildings. Looks at the Human Science Building at the University of Pretoria in this light.
